I am trying to develop very simple app for fleet of Airbnb apartments. I want to create simple to use auto apartment check in for any user with any kind of phone (it does not need to be a smartphone).

Idea is to have reserved SIP account online, that will trigger a web service on a ring on a specific number for specific apartment. It is pretty much easy when I set up port forwarding on a router (besides security issue), but I want to avoid that.

Is it possible to install, for example OVPN client on Vera, so I can call web service from OVPN server?

Does anyone have such experiences? Idea is to unlock an apartment on a regular phone call?

Is there any other, smarter solution for that? It needs to be scalable and very easy to maintain because apartments are in different cities, and it would require minimal technical skills for installation.

I am worried about accidental unlocks. Maybe ring to a specific number FROM a specific number?

Long Live UI5! (OK finally made the switch to UI7 in January 2018, and am pretty happy....)

I unlock my home regularly while I am gone.In fact I just ask Vera Concierge on my mobile to do that.You just need a lock connected to Vera ... and use the Remote access servers ...You can do this from Vera's Mobile app (or any of a number of other apps, including Vera Concierge).
